4. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to
the next step
5. If the cause is not visually evident, check for diagnostic trouble codes (DTCs) and refer to the DTC index

Symptom Chart

CAUTION: Do not apply any grease based products to any parking aid system connector or pins
NOTES:

Please note if this diagnosis is being carried out on a vehicle without a hard wired parking aid speaker, ensure the in car
infotainment system is fully functional and configured correctly


Parking aid sensors that are painted incorrectly and not to the manufacturer standards, will not be considered in any
warranty claim

Symptom Possible Causes Action
NOTE:
Permanent/Intermittent fault

Parking aid system not
functioning correctly. (No
DTCs displayed)
Front or rear parking aid
sensors dirty
Front or rear parking aid
sensor position incorrect
Front or rear parking aid
sensor incorrectly installed
Front or rear parking aid
sensor coupling rings not
installed/incorrectly installed
Parking aid control module or
parking aid sensor connector
not fully latched
Parking aid sensors painted
without being removed from
the bumper assembly or not
painted to the manufacturer
specification
Clean front or rear parking aid sensors
Check the front or parking aid rear sensor position
Check the front or rear parking aid sensor are
correctly installed
Check front or rear parking aid sensor coupling
rings are installed/installed correctly
Ensure all parking aid system connectors are
correctly latched
Remove parking aid sensor and ensure correctly
painted parking aid sensor is installed
- Parking aid sensors that are painted
incorrectly and not to the manufacturer
standards, will not be considered in any
warranty claim
NOTE:
Permanent/Intermittent fault

Parking aid system not
functioning correctly. (No
DTCs displayed). System
characteristics or
environmental effects
Parking aid sensors incorrectly
mounted
Incorrect vehicle ride height
Dirty parking aid sensor face.
Ice/snow covered sensor.
Debris trapped between
parking aid sensor and
parking aid sensor body.
Heavy rain or water splash
from the ground
Non standard, bumper,
exhausts/tailpipes, tow bar or
external spare wheel
mounting
Area around vehicle is not
clear of obstacles such as
channels, gutters or other
items on the ground
Exhaust gas and warm air
clouds creating ghost echoes
Vehicle not on level ground or
next to a gradient
Parking aid sensors painted
without being removed from
the bumper assembly or not
painted to the manufacturer
specification
Ensure the sensors are a tight fit in the holder and
locked. Ensure the sensors are central in the holder
and bumper and at the correct angle
Ensure vehicle ride height is within the specified
limits. Rectify as required
Clean the sensor face as required. Defrost the
sensor and dry as required. Clear any debris from
the sensor and holder as required. Water flowing
over the sensor is a system limitation. (no action
required)
Check for non standard, bumper, exhausts/tailpipe,
tow bar or external spare wheel mounting that may
be being detected by the parking aid system.
Rectify as required
Ensure the area around the vehicle is clear of any
obstacles, move the vehicle to a suitable area
before continuing diagnosis
Ensure no exhaust gas or warm area clouds are in
the area around the parking aid sensor detection
range
Ensure the vehicle is on level ground and clear of
any ramps, potholes or speed bumps, move the
vehicle to a suitable area before continuing
diagnosis
Remove parking aid sensor and ensure correctly
painted parking aid sensor is installed
- Parking aid sensors that are painted
incorrectly and not to the manufacturer
standards, will not be considered in any
warranty claim

PINPOINT TEST B : PARKING AID SYSTEM NOT FUNCTIONING CORRECTLY WITH NO DTCS LOGGED TEST
CONDITIONS DETAILS/RESULTS/ACTIONS B1: PARKING AID SYSTEM GIVES WARNING SIGNAL WITHOUT OBSTACLE 1 Clean the parking aid sensor face. Check for any damage to the parking aid sensor face.

thickness. Rectify as required Parking aid system functioning correctly? Yes
No further action required
No
GO to B2. B2: PARKING AID SYSTEM GIVES WARNING SIGNAL WITHOUT OBSTACLE 1 Ensure the vehicle ride height is within manufacturer specified limits. Rectify as required Parking aid system functioning correctly? Yes
No further action required
No
GO to B3. B3: PARKING AID SYSTEM GIVES WARNING SIGNAL WITHOUT OBSTACLE 1 Check for any non standard accessories are not fitted, such as tow bar, bike rack, body kit, modified exhaust, lighting or licence plate holder Parking aid system functioning correctly? Yes
No further action required
No
GO to B4. B4: PARKING AID SYSTEM GIVES WARNING SIGNAL WITHOUT OBSTACLE 1 Limitations or characteristics of the parking aid system such as vehicle on a gradient, exhaust gas vapour, signal reflection Parking aid system functioning correctly? Yes
No further action required
No
For a detailed description of the parking aid system, refer to the relevant description and operation
section in the workshop manual.
REFER to: Parking Aid (413-13 Parking Aid, Description and Operation). DTC Index


CAUTION: Diagnosis by substitution from a donor vehicle is NOT acceptable. Substitution of control modules does not
guarantee confirmation of a fault, and may also cause additional faults in the vehicle being tested and/or the donor vehicle.
NOTES:


If the control module is suspect and the vehicle remains under manufacturer warranty, refer to the Warranty Policy and
Procedures manual (section B1.2), or determine if any prior approval programme is in operation, prior to the installation of a
new module.


Generic scan tools may not read the codes listed, or may read only five digit codes. Match the five digits from the scan
tool to the first five digits of the seven digit code listed to identify the fault (the last two digits give additional information
read by the manufacturer approved diagnostic system).


When performing voltage or resistance tests, always use a digital multimeter (DMM) accurate to three decimal places,
and with an up-to-date calibration certificate. When testing resistance always take the resistance of the DMM leads into
account.


Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests.


Inspect connectors for signs of water ingress, and pins for damage and/or corrosion.


If DTCs are recorded and, after performing the pinpoint tests, a fault is not present, an intermittent concern may be the
cause. Always check for loose connections and corroded terminals. Parking aid system functioning correctly
Yes
No further action required
